When the sensors are activated, the parking
sensor display screen appears in the
instrument cluster.
Parking Sensor Display Screen
Obstacle presence and distance information is
therefore provided both by the acoustic signal
and the instrument cluster display.
The system indicates a detected obstacle by
displaying an arc in one or more positions
according to the distance of the obstacle and its
position in relation to the vehicle.
If an obstacle is detected in the rear central
area, the instrument cluster display shows all
the arcs in the rear central area, up to the one
that corresponds to the position of the obstacle
itself.
— I
The signal is similar for obstacles in the rear left
F
or right area. The arc that corresponds to the
position of the obstacle will flash. The color on
the instrument cluster display depends on the
distance from and position of the obstacle.
The vehicle is close to the obstacle when the
instrument cluster display shows a single
constant arc and emits a continuous sound. If
there are several obstacles, the closest one is
indicated.
A
CTIVATION
The sensors are automatically activated when
REVERSE gear is engaged and a visual display
will appear in the instrument cluster display. As
the obstacle behind the vehicle gets closer, the
acoustic signal becomes more frequent.

NDICATION
Parking sensor failures, if any, will be indicated
when REVERSE gear is engaged by the
illumination of the
instrument cluster display.
G
ENERAL
When parking, take the utmost care over
obstacles that may be above or under the
sensor.

ARNINGS
Under certain circumstances, objects close to
the vehicle are not detected by the system and
could therefore cause damage to the vehicle or
be damaged themselves.
Some conditions may influence the
performance of the parking sensors:
The presence of ice, snow, mud or multiple
layers of paint on the sensor surface may
cause reduced sensitivity of the sensor itself
and therefore reduce the system perfor-
mance.
Mechanical interference (e.g. washing the
vehicle, rain, strong wind, hail) may cause the
sensor to detect a non-existent obstacle
("echo interference").
The presence of ultrasonic systems (e.g.
pneumatic brake systems of trucks or pneu-
matic drills) near the vehicle could alter the
signals sent by the sensor.
The variation in sensor position, caused by
variation in ride (due to suspension compo-
nent wear), changing tires, overloaded
vehicle, or tuning that lowers the vehicle, for
example, may affect parking sensor system
performance.
